Specification of Letters Patent.

GLUIN G-ROLL.

Application filed February 14, 1913. Serial No. 748,346.

To all whom it may concern Be it known that I, EDWIN G. STAUDE, a citizen of the United States, resident of Minneapolis, Hennepin county, Minnesota,

have inventedcertain new and useful Improvements in Gluing-Rolls, of which the;

' the way 4, thereby to maintain the sleeve following isa specification.

My invention relates to means for applying glue to the surface a blank orfother articlef a The object of-the inventionis to provide a gluing means capable'of rapid, convenient adjustment to'adapt it for gluing surfaces of varying sizes and shapes.

A further object 1s to provide means for evenly distributing the glue wlthout smearing and without using a greater quantity of glue than necessary-for the blank surface.

A further object is to provide a gluing.

means adaptedfor applying'glu'e to surfaces generally, but particularly adapted for .glu-

ing the fiapsof-envelop blanks.

My inventionconsists generally in various constructions and Combinations, all as hereinafter described and particularly pointed out in theclaims. I r.

In the accompanying drawings formmg part of this specification, Figure l is a plan I viewfofa sectional gluing roll embodying my invention, Fig. 2 is-a sectional view,

showing the "preferred means for mounting I thesections of-the roll on a shaft, Fig. 3 is an end view of the roll, Fig. 4c is a per'spective view of aportion of the roll, with the shaft "removed, illustrating the manner of adjusting the roll segments, Fig. 5 is a plan View of a gluing roll showing a modified construction, Fig. 6 is a sectional view of the same, Fig. 7 is an end View of the modified construction, Fig. 8 is an end View, showing anothermodification in the construction of the roll, Fig. 9 is a plan view of'the modified I construction shown in Fig. 8, Fig. 10 is a detail view, showing the manner of mount ing the gluing points of Fig. 1 in the edges of thesegments, Fig. 11 is a detail sectional view, showing the preferred manner of mounting the gluing surfaces of the modification shown'in Fig. 8, in the surfaces of the quadrants shown 'in said figure.

In the drawings, 2 represents a shaft. I

3 is a key'ada ted to slide in a way 4 2 and 5 is a sleeve that is secured to the key. 3 by any suitable means, such as the screw 6. 7 isa set screw mountwhile the set screw 7 carried by said sleeve bears against the other end of said key to press the same firmly against the bottom of and key in the desired position of longitudinal adjustment onthe shaft. One end of j the sleeve 5 is preferably provided with an annular flange 8 and the opposite end of the sleeve is threaded to receive a lock nut 9.

Between thisfiange and lock nut I provide a series of roll sections or segments 10 hav ing hubs ll-provided with rabbetededges 12 to allow the hubs to nest or interlock with one another on the sleeve 5. The hubs operate to hold the segments in place on the sleeve and allow them to be rotated for the different adjustments of the gluing surfaces. The ends of the segments are adapted to lap by one another, as indicated in Fig. 4, to allow their rotary adjustment on the sleeve, and each segment is provided with a socket 13 therein adapted to receive a gluing point or plug '14 which projects slightly'beyond the peripheral surface of its segment and is adapted to receive glue from any suitable means for application to a blank and particularly to the flap of an envelop blank. These gluing points or surfaces are preferably arranged as indicated in Fig. 1, in diverging rows, running crosswise of the segments'to adapt them for the applioationof glue to the triangular section of a blank, such as the flap of an envelop. The segments are preferably provided with curved slots 15 to receive clamping bolts 16 by means of which the segments may be held which are locked together by the other bolt,

the curved slots 15 being of suflicient length to allow the required degree of rotary .ad-

'justment. I am thus able to quickly adjust the points or gluing surfaces of one row toward or from the corresponding points of 'the other row and thereby adapt the gluing roll for varying angles of the edges to be glued, and in the case of envelops, for different lengths of flaps and diflerent shapes thereof.

The gluing points maybe made of any suitable material, preferably rubber, and will apply the glue in the desired quantity upon a surface, such as the edge of a blank or an envelop flap.

;In Figs. 5 and 6 I have shown a modified construction of the gluing roll, consisting of a hub 17 mounted on a shaft 18 in substantially the same manner as described with reference to Figs. 1 and 2, said hub being provided with an annular flange 19 between which and a clamping plate 20, secured to the other end of the hub by screws 21, a series of segments 22 are arranged. These segments are also arranged in groups, as in the construction above described, with a space provided between" the adjacent ends of the groups, and this space is preferably bridged by a series of rings 23 arranged between the abutting ,edges of the segments and extending entirely around the hub, be-

ingheld thereon by the pressure of the segments upon one another. Upon loosening the screws 21, the pressure on the segments will be relie ed and they may be adjusted endwise between the rings toada'pt the glu- I ing points, corresponding to those described in the preferred construction, to the varying shapes and angles of the surfaces or flaps to which the glue is to'be applied. The

outer segmentsj .ajre preferably-made'wider I at the base to enter'recesses 24 formed in the flange 19 and the clamping plate 20.

In Figs. 8 and 9- I have shown another eecmodification in the construction of the gluquadrants Y clamped on a shaft 27 by means of a clamping device, which consists in a pair of 25 having hub sections .26

ing screw 28. The faces of these quadrants are each provided-With aseries of diagonally arranged parallel grooves 29 which are dovetailed in form and each provided with a slide. 30 having'bevelededges to fit the walls of the groove. A gluing block 31 is seated upon the quadrant over each groove therein and is held in place by means of a clamping screw 32which passes through the block and is tapped into the slide 30. When this screw, is tightened, the block 31 will be locked firmly on the surface of the quadrantand when the screw is loosened the block with the slide 30 may be moved back and forth in its groove toward or from the corresponding block on the other quadrant.

The head of the screw is preferably flush with the surface' of the block and forms therewith a gluing surface or point which, when supplied with glue, is adapted to apply it to a blank such as the flap of an envelop or wherever it is desired to apply glue to a surface. As indicated in Fig. this construction of the gluing device provides for a wide range of adjustment of the gluing surfaces for I may adjust the blocks 31 so that those of one quadrant-will be in line with the blocks of theother quadrant or at The angular arrangement of the gluing points or surfaces, as shown in the drawings, 'adapts the dev ce partlcularly for applying glue to the triangular flaps of envelop blanks, but I do not confine myself to this use, as the device may be used wherever it is desired to apply glue to surfacesor to the edges of blanks, particularly where relative adjustment ofthe gluing points is desirable to meet the varying shapes and sizes of the blanks to be glued.

- It is particularly to be noted that the first described form of my invention provides opposing series of adjustable peripherally disposed gumming members; the ad justment of any member of either series increases or decreases 1ts distance, measured peripherally, from the corresponding mem- ,ber of the other series, without moving said member out of the plane, transverse to the axis of the roll, which it occupies in commonwith the corresponding member of the other series.

I claim as my invention 1.

A gluing roll comprising roll segments {j arranged in groups, the segments of each group having curved slots thereinand bolts securing the segments of the same group together, the segments of each group being" capable of adjustment with respect to one: another and with'respect to the segments of the other group, said segmentshavingf' roll segments arranged in groups, the seg peripheral gluing surfaces.

4. A gluing roll comprising a series ments of one group having their endsv lapk ping by theadjacent segments of the other} group and capable of rotary adjustment with respect to one another, said" segments having peripheral gluing surfaces.

5. A gluing roll, comprising opposing series of segments, with the corresponding opposed segments of each series in planes transverse to the axis of said roll, a hub (in which said segments are angularly ad]ust able, and gumming members disposed on the vperipheries of said segments.
